- History:
-
- Modified by cmetz for OPIE 2.31. Use usleep() to delay after setting
- the terminal attributes; this might help certain buggy
- systems.
- Modified by cmetz for OPIE 2.3. Use TCSAFLUSH always.
- Modified by cmetz for OPIE 2.22. Replaced echo w/ flags.
- Really use FUNCTION.
- Modified by cmetz for OPIE 2.2. Use FUNCTION declaration et al.
- Flush extraneous characters up to eol. Handle gobs of possible
- erase and kill keys if on a terminal. To do so, use RAW
- terminal I/O and handle echo ourselves. (should also help
- DOS et al portability). Fixed include order. Re-did MSDOS
- and OS/2 includes. Set up VMIN and VTIME. Added some non-UNIX
- portability cruft. Limit backspacing and killing. In terminal
- mode, eat random other control characters. Added eof handling.
- Created at NRL for OPIE 2.2 from opiesubr.c. Change opiestrip_crlf to
- opiestripcrlf. Don't strip to seven bits.
